SPRING-TIRE.

I Specification of Letters Patent.

Application filed July 20, 1910. Serial No. 572,947.

Patented May 14,1912.

' To'aZl may concern zen of the United States, residing at Wina mac, inthe county of Pulaski and State of Indiana, have invented certain newand use- -f fill Improvements in Spring-Tires, of which the-following isa specification. My '1nvent1on relates to spring tires, of the 11' type;in which an outer tube or shoe is held 0,

in expanded condition by means of a metal- -lic spring element thereinand is designed to a provide a tire of this kind, especially adapt-.

- ed for vehicle use, which is simple and cheap of manufacture, andwhose resiliency is increased bythe particular construction. Tovarlousends set out, the lnvention consists of the elements, combinations, andarrangements of parts, all as will be hereinafter fully set forth andsuccinctly defined u the annexed, claim. a

In the accompanying drawings which are to be taken as a part of thisspecification and in whichlI have shown a merely preferred form ofembodiment of the invention, Figure 1 is a side elevation, partly insection of part of a wheel equipped with the invention; Fig.

. 2 is a sectional View on the line 2 2 of Fig. 1

is a similar view on line 33 of Fig.

. 1;, Fig. etis a detail view of the plate from which the circularsprings are formed;

' 5isa1detail perspective view of a section of the plate after it hasbeen formed ready for use; Fig. 6 is a detail perspective view of theretaining plate and Fig. 7 is a detail perspective view of a retainingbolt employed.

Referring more particularly to the drawings, the numeral 5 designatesthe rim of an ordinary automobil'ewheel on which 1s su1tably secured anouter caslng or the like 6 which is held in an extended position by aplurality of radial projecting substant1ally circular springs 7, themeeting ends of which are connected together as at 8, thereby Ymaintaining the projecting springs in a s aced position, thus avoidinthe possibility of them becomlng entang ed or allowing them to shiftfrom thelr relative position. Formed in the meeting edges of the springat intervals are cut out portions 9 which when brought together formslots-:10. Surrounding the outer face of the meeting ends of thecircular s rin is a circular band Beit'known that I, GEORGE Benson,citip therewith to allow the elongated heads 13 of.

a bolt 14 to be inserted therethrough and then turned at right anglesacross the slot 12, the slots in the circular band 11 are cut.

so as to be between the circular springs, the bolts 14 to be made toextend entirely through the rim of the wheel, and the nuts 1.5 tightenedto retain the said band 11 and the circular sprin s 7 securely againstthe periphery of the r1m, the band 11 is to have studs or lugs 17 eitherriveted or otherwise fastened thereto corresponding with the cen ter ofeach circular spring and prolonged a suitable distance within the circleto allow winner end of the coil springs 20 to be icld in place.

Surrounding the outer surface of the circular springs is a circular band16 of leather or any usual or preferred material of the necessary widthfirmly riveted or otherwise fastened to each of the circular springs, asat 18 and 19 the heads of the rivets to be prolonged so as to project asufficient distance within the circle to allow the outer ends of thecoil spring 20 to be held in place. It will be noted that. in the rim isformed or otherwise made a plurality of counter sunk slots 21 which areadapted to receive the heads of the bolts while the spring and adjacentparts are being placed in position after which said bolts are passedthrough said slots as stated. v

It is to be understood that this invention is not to be limited to thespecific forms, ma-

wheel rim, of an inclosing casing engaged therewith, a plurality ofspaced and bowed spring members located wlthm said casing and holdingsaid casing in distended posltion, opposed portions connecting the endsof all of said spring members to space and hold them in position, andnotches formed in the edgesofsaidportions slots pei ssiiig the rtaming'length of the' heads-of which exceeds the plate, said portions arebrought edge to edge, an the connecting portions and the rim. overlyingretaining PIMEG BXtEIIdiIIg entirely?!
